target vessel revascularization
A repeat intervention on the same coronary vessel previously treated with percutaneous coronary intervention.
Full Definition
Target vessel revascularization (TVR) refers to any repeat percutaneous or surgical intervention performed on the same epicardial coronary vessel that was previously treated during the index procedure. TVR is a key endpoint in interventional cardiology studies and represents either restenosis of the treated segment (target lesion revascularization) or progression of disease elsewhere in the same vessel. The need for TVR may indicate technical issues with the initial intervention, patient-related factors affecting healing, or natural disease progression. TVR rates are important quality metrics for interventional procedures and stent performance evaluation.
Usage
Usage note: Distinguish from target lesion revascularization, which is more specific to the exact treated segment.
